Definitions

  • the invention relates to a device on a sheet film cassette, in particular an X-ray film cassette for closing the cassette having a base part and a cover, with at least one slide with a spring held in the closed position with a hook, which engages behind a projection provided on the cover in the closed position; see. US-A-2,878,389.
  • cassette cover In the case of sheet film cassettes, the cassette cover is generally connected to the base part via a hinge at one edge, the locking elements then being located either on the side opposite the hinge or on the two sides starting from the hinge side.
  • cassettes are also known in which the cover is brought onto the base part essentially in a parallel orientation and is fastened by means of closure elements on at least two opposite sides.
  • the object of the invention is therefore to provide a device of the type mentioned at the beginning in which an easy and safe closing is to be made possible.
  • 1 denotes a base part of an X-ray film cassette, to which a cover 2 is articulated via a hinge (not shown).
  • sliders 3 and 4 are provided, which are guided in suitable guide means on a side wall of the base part 1.
  • Actuating elements or grips 3a and 4a are formed on the sliders 3 and 4, which are accessible from the outside through openings in this cover when the cover 2 is closed.
  • the sliders 3 and 4 can also be operated by hand by means of a pin 36 of an opening mechanism, which can strike the side surface of the handle 3a or 4a through a bore 5 in the side wall of the base part 1.
  • the slide 3 is displaceable in the direction of the arrow 6 and is held in the rest position shown by a tension spring 7 suspended on the base part.
  • the slide 4 is displaceable in the direction of arrow 8 and is held in the rest position shown by a tension spring 9 suspended on the cassette.
  • the sliders 3 and 4 have longitudinal slots 10 which run parallel to the directions of movement 6 and 8 and in which pins 11 attached to the side of the base part 1 are guided.
  • a projection 3b and 4b is formed on the opposite ends of the sliders 3 and 4, respectively.
  • One projection 3b is articulated at one end of a lever element 12 in the pivot point 13 and the other projection 4b at the other end of the lever element 12 in the pivot point 14, the lever element 12 in its center around an axis attached to the side wall of the base part 1 15 is rotatably mounted.
  • the lever element 12 is expediently designed as a small wheel, in which a radial slot is provided at the articulation points 13 and 14, in which pins attached to the projections 3b and 4b are guided.
  • Hooks 16 and 17 are formed on the slides 3 and 4, which in the rest position of the sliders 3 and 4 engage behind hooks 18 and 19 attached to the cover 2 for the purpose of closing.
  • an L-shaped rail 21 is connected, which guides the slide 3 on two sides and holds it against the side wall of the bottom part, not shown.
  • this rail 21 has a recess.
  • a projection 22 formed with an inclined surface 23.
  • a slot 24 is formed, in which an elastic pawl 25 is inserted.
  • the elastic pawl 25 has a holding part 25a lying in the slot 24, a resilient middle piece 25b and a hook-like projection 25c.
  • a nose 25d is also formed on the hook-like projection 25c.
  • the device according to the invention is also provided on the slide 4.
  • the device according to the invention can also be used on closures that are separate from one another.
